= Lithogenic silica
{wiki=Lithogenic_silica}
Lithogenic silica refers to silica (SiO₂) that originates from geological processes, particularly from the weathering of silicate minerals. It is primarily found in terrestrial environments and contributes to the formation of sedimentary rocks, such as sandstone and quartzite. Lithogenic silica is distinguished from biogenic silica, which is produced by biological processes, such as the accumulation of diatoms and other siliceous organisms in marine environments.
